SEPARABLE BUTTON.

SPECIFICATION forming part of Letters Patent No. 233,423, dated October 19, 1880. Application filed June 7, 1880. (No model.)

To all whom t'tmay concern:

Be it known that I, CHARLES E. MASON, of Attleborough, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Separable Buttons; and I do hereby declare that the following specification, taken in connection with the accompanying drawings, forming a part of the same, is a full, clear, and exact description thereof.

The invention hereinafter described relates to that class of buttons and studs which are made in two .separable parts for convenience of application and removal, and to that variety in which two locking devices are employed, whose inner ends engage the post to prevent the detachment of the parts, and whose outer ends project beyond the buttonhead, so as to be pressed by the fingers.

My improvement consists in providing the locking devices with elevated portions which receive the ends of the actuating-spring and hold said spring in position in the button-head, as will hereinafter appear.

Referring to the drawings, Figure 1 shows, in section, a sleeve-button embodying my improvement. Fig. 2 represents a view of the under side of the button-head. Fig. 3 shows the same with the cap-plate removed. Fig. 4 represents the locking devices in perspective, and Fig. 5 shows the blank from which said devices are formed.

A is the shell, forming the front of the button-head, the rim of which is perforated to receive the outer ends of the locking dewhich' engage said locking devices. D is a perforated cap-plate secured to the buttonhead and arranged to overlie the inner ends of the lockin g devices and retain them in vertical position. E is the stem attached to the button-head. F is the tubular post, having a flanged and beveled head, f, and G'lS the shoe secured to the post.

The locking devices B B are duplicates, and each is formed from a blank, B, Fig. 5, which is punched from sheet metal. The inner end, b, of each device is enlarged laterally to allow of an extended engagement with the post, and is bent into the form of a hook, as shown in Figs. 1, 3, and 4. These devices are placed side by side, and are arranged to slide upon each other, being externally guided by lugs to upon the button-head, as shown in Fig. 3. The hooked ends b are in the same horizontal plane, and each end overlies the body portion of its fellow device, so that the said ends are in vertical alignment.

To obviate the necessity of an elevated central portion or member on the button-head, (common in this variety of buttons,) to accommodate the spring G and allow its bent ends properly to engage the locking devices B B, the said devices, near their outer ends, are provided with elevated portions 1), of sufficient height to allow the spring 0 to pass freely under, the said elevated portions being perforated to receive the spring ends, as shown in Figs. 1, 2, 3, and 4. These elevated portions b are so placed with relation to the rim of the button-head as to act as stops and hold the locking devices in the desired positions when they are disengaged from the post.

To retain the locking devices in their proper vertical position the capplate D is employed and secured to the button-head, the said cap-plate being perforated to receive the post F.

Although I have chosen to employ the lugs a to guide the locking devices laterally, I am aware that the said lugs may be dispensed with and the guiding be effected by a properly-formed cap-plate, D, bent so as to engage the sides of the locking devices and secured to the button-head.

From the foregoing description it will be seen that a central elevated portion or member on the button-head, to make room for the end of the post and accommodate the spring, is dispensed with; that the form of the ends I) b of the locking devices makes room for the end of the post, and the elevated portions 12 b accommodate the spring and hold it in position.

My improved button is simple and non-expensive in construction and perfectly reliable in use.

Having described my invention, what I claim, and desire to secure by Letters Patas described, the springC cap-plate D, post ent, is-- b F, and shoe G, substantially as set forth.

In a separable button, the com ination of the head A, the locking devices B B, pro- CHARLES MASON 5 vided with the perforated elevated portions Witnesses:
